GeoPark Ltd., Santiago, reported a gas field discovery in the Fell Block in Chile's Tierra del Fuego region. Part of the Dicky geological structure in the block, Jauke Oeste field opens the potential for multiple development drilling opportunities, the company said (OGJ Online, Aug. 20, 2018).
The Jauke Oeste 1 exploration well was drilled to 9,596 ft TD. A production test, through different choke sizes, in the Tobifera formation resulted in an average production rate of 4.4 MMscfd of gas (729 boe/d) and 52 bo/d of condensate with a wellhead pressure of 3,141 psi. Additional production history is required to determine stabilized flow rates of the well and the extent of the reservoir, the company said.
Surface facilities are in place, the well is in production, and the gas and condensate are being sold to offtakers.
Jauke Oeste lies about 1 km north of Jauke gas field, which is currently producing 8.4 MMscfd from two wells (1,400 boe/d). Jauke and Jauke Oeste gas fields are part of the Dicky geological structure in the block, opening the potential for multiple development drilling opportunities, GeoPark said.
Additional exploration activities with a focus on oil prospects will be carried out in Chile in this year’s first quarter. The company will spud the Leun 1 exploration well in the Flamenco Block (GeoPark operated, 100%) in February, to be followed by the Huillin 1 exploration well in the Isla Norte Block (GeoPark operated, 60%), and the Koo 1 exploration well in the Campanario Block (GeoPark operated, 50%).
GeoPark is operator of the Fell block with 100% interest.
